Django Test (StaticLiveServerTestCase) returns 404
I have a project which uses Angular and Django and I am experiencing a weird behavior when I test my application using StaticLiveServerTestCase and Selenium. When I start testing it everything seems to work but, if I refresh the main page I receive a 404. So, if I test without base url it works, but once Angular adds the base url the test returns 404: http://127.0.0.1:8000/baseURL/test My URL is defined as follows: re_path('test', views.index, name='index') So, summarizing, when I test http://127.0.0.1:8000/test it works, but if I test http://127.0.0.1:8000/baseURL/test it does not -if I run my app normally, buth URLs work. According to my novice knowledge and as the url pattern is defined both urls should work. Obviously I am missing something else. Thanks in advance. Note: Test class if defined as follows: class Tests(StaticLiveServerTestCase): def set_chrome_options(cls): options = Options() options.add_experimental_option("useAutomationExtension", False) return options @classmethod def setUpClass(cls): cls.host = "127.0.0.1" cls.port = 8000 super(Tests, cls).setUpClass() cls.selenium = webdriver.Chrome(executable_path=settings.DRIVER_PATH, options=cls.set_chrome_options(cls)) ... -
How to handle file processing request in Django?
I am making a Django Rest framework based server and in one of the request, I get an audio file from front-end, on which I need to run some ML based algorithm(I have script for same) and respond back to user with the result. Problem is that this request might take 5-10 seconds to execute. I am trying to understand following things: Will Celery help me reduce the workload on server, as in any case I need to wait for the result of the ML Algo and respond back to user. Should I create a different server to handle this type of request? Will that be a better approach? Also, is my flow of doing things correct. First, Upload the file to some cloud platform for storage and serialize the instance to get the url of file. Second run the script using celery and wait for the result. Third, Respond back with the result. Thanks for helping. -
How to retrieve Page content from streamfield in Wagtail?
So, I've created SolutionPage page and inside It's content there is short_portfolio block. I added several ProjectPage instances via Wagtail admin panel to PageChooserBlock. class SolutionPage(Page): ... content = StreamField([ ... ... ('short_portfolio', blocks.StructBlock([ ('title', blocks.CharBlock(required=False)), ('description', blocks.RichTextBlock(required=True)), ('projects', blocks.StreamBlock([ ('project', blocks.PageChooserBlock(ProjectPage)), ], required=False, max_num=4)), ])), ], blank=True, null=True, validators=[UniqueProjectsInShortPortfolioValidator()]) Now, I'm working on API view for PDF export and I need to extract all ProjectPage objects from a given SolutionPage import requests from django.conf import settings from django.http import HttpResponse from django.shortcuts import render from rest_framework import views from rest_framework.generics import get_object_or_404 from portfolio.models import ProjectPage from solutions.models import SolutionPage class PortfolioToPdfView(views.APIView): def get(self, request, *args, **kwargs): def get_404(): return HttpResponse( render( request=None, template_name='404.html', content_type="text/html" ), content_type='text/html' ) path = request.META['PATH_INFO'] if path.find('solutions') == -1: return get_404() slug = path[path[1:].find('/') + 2:] slug = slug[:slug.find('/')] solution_page = get_object_or_404(SolutionPage, slug=slug) short_portfolio = solution_page.content.stream_block.child_blocks["short_portfolio"] projects = [project.child_blocks["project"].target_model for project in short_portfolio.child_blocks["projects"]] ... response = HttpResponse(request, content_type='application/pdf') return response The problem is that in this way I can only extract something like a "schema" of the page but not it's actual content.

manage.py flush not working during testing
I am using the tutorial on how to use Django Rest - React and it has some testing in it too. When I test it, error comes as: CypressError: cy.exec('npm run dev') timed out after waiting 60000ms. Because this error occurred during a 'before all' hook we are skipping the remaining tests in the current suite: 'Django REST framework / Rea...'

Wrong default value for some dropdowns in django admin
I am seeing wrong default values for some dropdown fields in the Django admin, both in table and form view. Is there a known issue about this? The problem seems to be happening with some of my model fields, but not with other fields. Even though they are similarly defined. To be clear: the dropdown is properly populated, but the default value is wrong (does not correspond to the value in the database, but it is set to the non-defined value, which in the admin appears as ------ I am using Django 2.1 -
different request.POST on same page causing DeleteView error Django
My Django 2 app using Django Channels has a ThreadView or a page that displays a messaging thread between two users, with URL re_path(r"^(?P<username>[\w.@+-]+)", chat_views.ThreadView.as_view(), name='thread'), There is a text input form at the bottom of the page to submit a new message via request.POST which is handled via the ThreadView. I think the problem is arising when I try to put a request.POST delete form (DeleteView) on the page as well in order to delete the thread, URL path('<int:pk>/delete/', chat_views.ThreadDeleteView.as_view(), name='thread_delete'), When the delete form is submitted, I get the error DoesNotExist at /messages/2/delete/ User matching query does not exist.

noob question: how do I add the DJANGO_SETTINGS_MODULE from within a python script?
Apologies for a basic question but I honestly haven't found an actionable answer yet even though I'm sure this is a simple solve. I'm calling a python file which is part of a Django app (same folder as the models, views etc) from the command line, from a totally different working directory. The python file is called as a module and not as a package since I'm not using the "-m" argument. The python file imports from the models file, upon which I get a long Traceback through the init files etc ending in the below error: django.core.exceptions.ImproperlyConfigured: Requested setting INSTALLED_APPS, but settings are not configured. You must either define the environment variable DJANGO_SETTINGS_MODULE or call settings.configure() before accessing settings. So I'm adding the following line in the python file before the import statement: import os os.environ.setdefault('DJANGO_SETTINGS_MODULE', "C:/Users/oktested/further_file_path/settings") Basically I'm putting the entire path to the settings.py file in there, without the .py extension. But upon doing this I get a ModuleNotFoundError: No module named 'C:\Users\oktested\'. How do I express the path to the settings.py file that already exists in my Django project? I am using Django 2.1 on Windows 10 FYI. -

I will roughly describe the problem: I have a React.js application, which authenticates using IDAM and receives a token. I can use this token to make requests to the backend API. Everything is fine on the React.js side. Now I need to redirect to a Django application from the React.js application. I already have the authentication token, and I want to pass it to the Django application. I was thinking about putting the authentication header when doing window.open to open the Django url, but I realize that it is not possible to put headers with window.open. How can I pass the authentication headers when opening a new url?
